Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Armed with a computer model in 1935, one could probably have written the exact same story on California drought as appears today in the Washington Post some 80 years ago, prompted by the very similar outlier temperatures of 1934 and 2014.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

And I am very upset that the OECD gets a giant $100 million-plus subsidy every year from American taxpayers. For all intents and purposes, we’re paying for a bunch of left-wing bureaucrats so they can recommend that the United States adopt that policies that have caused so much misery in Europe. And to add insult to injury, these socialist pencil pushers receive tax-free salaries.

And now, just when you thought things couldn’t get worse, the OECD has opened a new front in its battle against free markets. The bureaucrats from Paris have climbed into bed with the hard left at the AFL-CIO and are pushing a class-warfare agenda. Next Wednesday, the two organizations will be at the union’s headquarters for a panel on “Divided We Stand - Tackling Growing Inequality Now.”

Co-sponsoring a panel at the AFL-CIO’s offices, it should be noted, doesn’t necessarily make an organization guilty of left-wing activism and misuse of American tax dollars. But when you look at other information on the OECD’s website, it quickly becomes apparent that the Paris-based bureaucracy has launched a new project to promote class-warfare.

Over the last two decades, there was a move away from highly progressive income tax rates and net wealth taxes in many countries. As top earners now have a greater capacity to pay taxes than before, some governments are re-examining their tax systems to ensure that wealthier individuals contribute their fair share of the tax burden. This aim can be achieved in several different ways. They include not only the possibility of raising marginal tax rates on the rich but also…reassessing the role of taxes on all forms of property and wealth.

The OECD underlines the need for governments to review their tax systems to ensure that wealthier individuals contribute their fair share of the tax burden. This can be achieved by raising marginal tax rates on the rich.

Like Obama, the folks at the OECD like to talk about “fair share.” These passages sounds like they could have been taken from one of Obama’s hate-and-envy speeches on class warfare.

But the fact that a bunch of Europeans support Obama’s efforts to Europeanize America is not a surprise. The point of this post is that the OECD shouldn’t be using American tax dollars to promote Obama’s class-warfare agenda.

One last point is that the video was produced more than one year ago, which was not only before this new class-warfare campaign, but also before the OECD began promoting a global tax organization designed to undermine national sovereignty and promote higher taxes and bigger government.

In other words, the OECD is far more destructive and pernicious than you think.

Almost a thousand days into his term, President Obama has at last submitted the trade agreements with South Korea, Colombia, and Panama for an up or down vote in Congress.

All three agreements appear to have majority support in both the House and the Senate. Organized labor is putting up its usual anti-free-trade fight against all three, with AFL-CIO boss Richard Trumka coming out swinging in a Politico op-ed this week. He makes the standard union argument that Colombia is an unworthy free-trade partner because of ongoing violence against union members in that country.

In a Free Trade Bulletin earlier this year, my Cato colleague Juan Carlos Hidalgo and I examined the commercial benefits of the agreement with Colombia as well as the hollowness of the union charge. In the past decade, Colombia has made tremendous progress against violence in general, and especially violence aimed at union members. In fact, as we write in the FTB:

The statistics on the number of killings against union members vary depending on the source, with the figure from the government’s Ministry of Social Protection being lower than that of the National Union School (ENS for its acronym in Spanish), a Colombian nongovernmental organization affiliated with the labor movement. However, both sources show a steep decline in the number of killings since 2001. Moreover, when compared with the total number of homicides in the country, killings of union members clearly have dropped at a faster rate than those of the general population (see Figure 1).

Critics of the FTA fail to recognize that violent crime affects all levels of Colombian society, not only trade unions. What is more, the statistics show that union members enjoy more security than the population at large.

Looking at the homicide rate as defined by the number of murders per 100,000 inhabitants, the rate for the total population in 2010 was 33.9 per 100,000, whereas the rate for union killings was 5.3 per 100,000 unionists that same year (using the statistics of the ENS). That means that the homicide rate for the overall population is 6 times higher than that for union members.

Having just returned from a speaking trip last week to Medellín, Colombia, I can vouch that, after a difficult period of battling Marxist guerrillas and drug cartels, Colombia has once again become a normal country with a growing economy. Medellín is a bustling, business-oriented city with the usual challenges of traffic congestion. The students I spoke with at EAFIT University seemed eager for closer ties with the United States, and they do not understand why it has taken almost five years since the signing of the agreement for Congress to schedule a vote on it.

As I explained in an interview with the city’s leading newspaper (conducted in English, but translated here in Spanish), the politicians in Washington have run out of excuses for not establishing free trade between our two countries.

To no great surprise, the Obama administration announced today that it has cut a deal with the government of Colombia to address concerns about labor protections and to finally move toward enacting the long-stalled free-trade agreement between our two countries. This is welcome news for trade expansion and for strengthening our ties to a key Latin American ally.

Colombian President Juan Manuel Santos is expected to arrive later this week in Washington to cement the deal. In exchange for the agreement, Colombia has reportedly agreed to expand its efforts to protect union members from violence and to more vigorously prosecute those responsible.

As my Cato colleague Juan Carlos Hidalgo and I documented in a Cato study earlier this year, concerns about labor protections were never a valid reason for holding up this agreement. The overall murder rate in Colombia has declined dramatically in the past decade, and the murder rate against members of labor unions has declined even more rapidly. A union member in Colombia today is one-sixth as likely to be a victim of homicide as a fellow citizen who does not belong to a union. Meanwhile, the Colombia government has increased convictions for homicides against union members by eight-fold in the past three years.

As Democratic Senators John Kerry and Max Baucus pointed out in an op-ed this week that endorsed the agreement, the International Labor Organization has certified that Colombia is complying with its international labor agreements.

The obstacle of labor violence was just a political smokescreen that had been raised by labor-union leaders in the United States looking for any shred of an argument to oppose the agreement. Even the agreement announced this week is not going to win over the AFL-CIO. The Colombia government could have raised a hundred murdered union members from the dead, and organized labor in American would still chant that not enough was being done.

The breakthrough this week clears the path for Congress to approve, by what I predict will be comfortable bipartisan majorities, the pending trade agreements with Colombia, Panama, and South Korea.

Sunday marked the third anniversary of the signing of a free trade agreement between the United States and Colombia. It is an embarrassment to our great nation that this agreement with an important Latin American ally still sits on the shelf three years later, a victim of congressional trade politics.

As my Cato colleague Juan Carlos Hidalgo and I argued in a 2008 Free Trade Bulletin, and as I wrote in a more recent op-ed, the FTA with Colombia is a win-win for Americans. It fully opens the Colombian market and its 44 million pro-American consumers to our exports, while deepening our ties with one of our most dependable allies in the Western Hemisphere.

The AFL-CIO and other opponents of the agreement demand that Colombia further reduce violence against trade unionist before approval can be considered, and the president and Democratic congressional leaders have dutifully agreed. Never mind that the number of trade union members murdered in traditionally violent Colombia has declined dramatically under President Alvaro Uribe. Congress and the administration keep moving the goal posts, much to the frustration of the Colombian government.

Meanwhile, since the agreement was signed, U.S. companies have paid $2.3 billion in unnecessary duties, according to the “Colombia Tariff Ticker” sponsored by the Latin America Trade Coalition. On the foreign policy front, Colombia faces continued threats from the Marxist FARC guerrilla movement and its anti-American neighbor, President Hugo Chavez of Venezuela.

Refusing to enact the trade agreement with Colombia only reinforces suspicions in Latin America that the U.S. government is unreliable.

President Obama is meeting today with a bipartisan group of lawmakers to talk about reforming our broken immigration system. The challenge for both parties will be whether they can overcome opposition within their respective bases to expanding legal immigration.

For Republicans, the chief opposition remains the faction of talk-radio-driven conservatives who just don’t like immigration, period, especially when it comes from Latin America. For Democrats, who now run Washington, the chief opposition to allowing more foreign workers to enter the country legally is represented by organized labor.

As the Wall Street Journal reports this morning, advocates of immigration reform “worry that Democrats will defer to the AFL-CIO on the issue of legal immigration. The labor confederation has opposed a robust guest-worker program or higher levels of legal immigration, fearing they would depress wages. A larger labor presence would splinter the coalition of business and pro-immigration groups that embraced past immigration efforts, only to see them falter in the Senate.”

As I’ve argued consistently in the past, immigration reform is not worth pursuing if it does not include expanding future flows of legal immigrants, both highly skilled and lower-skilled workers. If Congress confines itself to legalizing the 8 million or so workers already here illegally, with a vow to get tougher on enforcement, then we are just repeating the mistake of the 1986 Immigration Reform and Control Act.

We will know if President Obama and Democratic leaders in Congress are serious about fixing the problem of illegal immigration if they face down their labor-union allies and embrace a workable, market-oriented expansion of legal immigration. Otherwise, we are in for more futility, frustration and failure.
